A walk through Paradise

Lupines, Indian paintbrush, and white daisies cover
the meadows of Paradise in mid-summer.

My second home has always been in Washington State.  My Dad first took me up there from our home in California when I was about 6 or 7, and I have returned many times since.  They only things I remember were sleeping under a makeshift tent under a giant fallen tree trunk, and buying a small figurine of a black bear as a souvenir.  After I became a plant geek at the ripe old age of 12, our family trips to Washington were exciting times of botanical discovery.  Washington is indeed a botanical paradise, and nestled on the side of Mt. Rainier, at about 5400 feet elevation, is the actual, real Paradise - it says so on the sign at the end of the road!  The explorer who named this complex of alpine meadows must also have been a lover of wildflowers, for nowhere else can one see such a lavish display.

Paradise is covered with up to 20 feet of snow from October through May, but through the brief summer there is a constantly shifting display as different species put forth their blossoms to attract their time-share of local pollinators.  Similar displays, but varying in the species composition, can be found in the alpine zones throughout the state, grading into the floras of Oregon and California to the south and British Columbia and Alaska to the north.  In future installments, I will get to some of these other places, but I begin with the epicenter of Paradise.  And there's no need for further chatter - I'll let the pictures speak for themselves.

In late May, the wildflower season is still weeks away.

The national park staff who stay through the winter might
be able to enter and exit buildings through the
upstairs windows.

The columbia or tiger lily, Lilium columbianum,
is one of the treasures to spot in sunny
spots in the forest along the road to
Paradise.

My favorite wildflower of all, Aquilegia
formosana, can be seen along roadsides and
in sheltered spots among the alpine
meadows.

Glacier lilies, Erythronium pallidum, are typically the first
flowers to appear as the snow melts.

Avalanche lilies, Erythronium montanum,  are close relatives
of the glacier lilies.

Anemone occidentalis emerges with
the glacier and avalanche lilies as the
snow melts.

Ranunculus eschscholtzii brightens up a spot
of bare ground.

Sedum oreganum grows on rocky
outcrops, and is common along the
road to Paradise.

Indian paintbrush, Castilleja miniata, brings color to many
parts of Washington.

Dense leafy shoots of Veratrum
viride arise in the spring.

The small, green, lily-like flowers of
Veratrum viride appear in massive
inflorescences in mid-summer.

Veronica cusickii provides blue accents
in the meadows of Paradise.

A shooting star, of the genus Dodecatheon,
appear to be diving toward the ground.

The yellow monkey flower, Mimulus caespitosus, pokes out
from among rocks.

An alpine willow is one of the few shrubs to be found at
Paradise.

Pedicularis bracteosa, the bracted
lousewort.

Penstemon menziesii is found in rocky,
exposed parts of the meadow.

Streams dissect the Paradise meadows, forming
cascades and small waterfalls as they descend.

In the 1960's there were some accessible ice caves under the
glaciers around Paradise.

At Sunrise, on the opposite side of Mt. Rainier from Paradise, the meadows are a bit drier.

The Carnivorous Plants of Florida

Pitcher plants of the genus Sarracenia
catch insects in hollow fluid-filled
leaves, and have large red, yellow, or
pink flowers.

I live in Florida, and was delighted to find out a number of years ago that we host here the greatest concentration of carnivorous plants in the United States. As the name implies, carnivorous plants capture digest, and consume animals, mostly small animals like insects.  Everyone knows the famous venus fly trap (Dionaea muscipula), which snaps shut quickly around an insect that touches its sensitive trigger hairs.  That is one species that unfortunately does not grow naturally in Florida, though I've heard rumors of carnivorous plant enthusiasts secretly planting it in some of our bogs that may be similar to its native habitat in North and South Carolina.

What we do have here are six species of pitcher plants (Sarracenia), five species of sundew (Drosera), six species of butterwort (Pinguicula), and 14 species of bladderwort (Utricularia).  Each is different in how it catches its prey.

Sarracenia flava is known to produce an alkaloid
drug that renders insect prey unable to crawl out of
the trap.

The opening of the pitcher invites insects with mottled
coloration and prevents their escape with small, slippery
hairs.

The pitcher plants have inflated, hollow leaves that fill with water.  Insects fall or slide into these pitchers, often attracted by bright colors, nectar or scent.  The walls of the pitchers are slippery due to wax or downward pointing hairs, so that insects that fall in cannot crawl back out.  At least one species, S. flava, has been found to secrete an alkaloid drug that inhibits the insects' ability to find their way out.  Some pitchers produce digestive enzymes, others rely on bacteria and fungi to breakdown the animal tissues.  The nutrients released can then be absorbed by the cells lining the chamber.  Some of our Sarracenias, such as S. purpurea and S. leucophylla, are wide open to rain water, which keeps them full at least during the rainy season.  Others have lids, that keep out some of the rain, or curved tops that keep out most of the rain (S. minor, S. psittacina).  These latter may be keeping a tighter control on the concentration of digestive fluids, and secrete fluids into their chambers from their own tissues.

Sarracenia purpurea collects rainwater to fill its traps.  This is the most widespread species,
extending from the Florida panhandle all the way up into Canada.

The traps of Sarracenia psitticina lay along the ground and when flooded
can catch small fish and other aquatic animals.

Sarracenia leucophylla occurs in the Florida panhandle and neighboring states,
 like most of the other species.

Sarracenia minor has a curved top that limits the amount of rainwater that can get into the trap.  This is the only species occurring south of the Florida panhandle region, and is found as far south as Hillsborough and Highlands Counties.

The long, grayish strands in this boggy roadside
are leaves of Drosera tracyi.

Drosera capillaris is common on wet
sandy slopes throughout Florida.

The leaves of sundews are covered with conspicuous glandular hairs.  Insects get caught in the sticky secretions and then are digested by enzymes in the secretions.  Two species (Drosera tracyi and D. filiformis) with long, slender leaves are found in the far north of the state.  The others have roundish leaves.  Drosera capillaris is abundant throughout the state, quickly colonizing marshy areas around bodies of water (see To self or not to self, the story of Drosera capillaris on the Botany Professor main page). D. brevifolia is less common, but appears to be tolerant of slightly drier soil.  D. intermedia, with longer leaves, lives in standing water.

Drosera brevifolia is similar to D.
capillaris, but flowers tend to be
larger and there are sticky glands
on the flower stalk.

The leaves of Drosera tracyi and D. filiformis
unroll like the fiddleheads of a fern frond.

Pinguicula pumila is common in central
Florida and comes with white, bluish, or
purplish flowers.

The traps of Pinguicula are simple, sticky
leaves.

In the butterworts (Pinguicula), the leaves are covered with short glands which give them a sticky, fly-paper like coating.  The flowers are variously yellow, white, blue or violet, usually with a conspicuous nectar spur, and they live in wet to boggy soil.

Pinguicula caerulea has sky blue flowers.

The flowers of Utricularia inflata emerge from
star-like floating rosettes.  Large, highly-
dissected trap-bearing leaves are beneath.

Utricularia subulata grows on wet sand,
often near Drosera capillaris.

Utricularia gibba is invisible until it sends
up its tiny yellow flowers.

The bladderworts (Utricularia) are the most numerous of Florida carnivores, with 14 species.  They get their name from the tiny bladder-like traps on their underwater or subterranean leaves.  These traps create a partial vacuum by actively pumping water out.  when tiny crustaceans brush against sensitive trigger hairs, they are sucked into the traps where they are digested.  Utricularia floridana, U. foliosa, U. inflata, and U. radiata are relatively large underwater plants, with just their flowers sticking up into the air.  U. olivacaea forms fine floating mats with tiny white flowers.  The others form their masses of traps in wet soil.  Bladderworts are cousins of the snapdragons and have similar yellow or purple flowers.

Springtime in New Mexico

Winter was not over yet in the Sangre de Cristo Mountains near Santa Fe.

Fifteen years ago, my wife had business in Santa Fe, New Mexico, and so I tagged along with camera in hand.  It was April, and I was hoping to find some signs of spring.

The famous Rocky Mountain aspens
(Populus tremuloides)
were still bare and snowbound.

At first it looked rather barren.  There had not been a lot of rain recently, and I wondered whether there was in fact a spring (botanically speaking) in the semi-arid parts of the state.  A little research on the internet shows that there is much more rain in the summer and fall than in the winter and spring.

At the Rio Grande Botanical Garden,
native redbud (Cercis) trees are
paired with cultivated pansies.

Tulip species from the Mediterranean
region were a highlight at the botanical
garden.

A quick run into the local mountains, the southern tail of the Rockies, confirmed that it was too early.  Snow still covered large areas, and the famous Aspen trees were still bare. So I began poking around the Rio Grande valley, Albuquerque basin and the mesas around Santa Fe, and  managed to find quite a lot. There were moist spots here and there with colorful annual and perennial herbs, and some plants that apparently didn't care whether it had rained recently in the drier areas.  Of course, there was plenty of color to be had at the Rio Grande Botanical Garden in Albuquerque, much of it not native, but nevertheless a welcome oasis in this dry region.

At Bandelier National Monument along the Rio Grande, the cottonwoods, relatives of the aspens, were just coming into bloom.  Hummingbirds buzzing and fighting with one another around the feeders at the visitor's center were a great treat.  Perhaps they also fed on the currant flowers that were also coming into bloom. Along the river were also thickets of Tamarisk, a shrub with scale-like leaves and tiny flowers.

Hummingbirds put on a constant show around the feeders
at Bandelier National Monument.

Low to mid-elevations around Santa Fe were dominated by pinyon pines,
and appeared to be quite dry in April of 1998.

Currants, or Gooseberries (genus Ribes) are shrubs growing along rivers.
