Allium tricoccum, Wild Leek -- Leafs first in the early spring and then in summer after the leaves have senesced, puts up a flowering stalk.

Allium tricoccum seeds are produced in mid autumn.

Hemerocallis (Hemerocallidaceae, Asparagales) contractile roots. This was 5 cm deeper after approximately 10 months (1/3/94 - 10/27/94). Contractile roots act by expanding laterally and shrinking in length. Lilies, Daffodils, Crocuses, Dandelions (yes dandelions!) have contractile roots!From Putz, N. 1998. Underground plant movement. V. Contractile root tubers and their importance to the mobility of Hemerocallis fulva L. (Hemerocallidaceae). Int. J. Plant Sci. 159: 23-30.

Hemerocallus if planted too deep will move up. By making a long shoot with only scale leaves, developing adventitious roots higher up and aborting the older section of shoot and roots.

Smilacina stellata

Smilacina racemosa

Ruscus “leaves” are modified flattened photosynthetic branches. Note flowers come right out of these branches!

Stems of Ruscus were bundled to clean butcher’s blocks. Hence the name Butcher’s Broom Family
