having leaves that become whiter as the season progresses; i.e., H. ‘Gold Standard’.
the upper part of the stamen, male flower part, in a capsule-like
structure, that splits to release yellow pollen.
asexual seed produced without the normal fusion of pollen and egg
giving rise to seedlings genetically identical to the pod parent; e.g., H.
coming from the joint of a leaf and the stem.
the mutation of a plant or division from a more complicated
state to a more natural state; the pigment change of a division from a
variegated (or less pigmented) state to a solid-colored (more chlorophyll)
1. flower. 2. waxy coating on a leaf, stem, or pod surface producing
a dusty appearance.
the time period between when the first flower of a stem or clump
opens or is receptive to pollination and the last flower is open or receptive.
the diminutive modified leaf or leaflike structure on the flower stem
below each flower.
the dying out of the middle portion of a clump.
an individual containing cells of two or more different tissues.
(in Hosta) changing position of the cells between
different tissue layers in an individual, ie., a goldmargined hosta producing
a gold-centered, all-green, or all-gold division.
a group of genetically identical individuals produced by asexual
(in Hosta) the collective set of petals and sepals, fused into
tepals, normally six, appearing as two sets of three.
the base of a plant where the roots and shoots join.
contraction for “cultivated variety”; a plant that is clearly
distinguished by identical physical characteristics and maintains these
characteristics through proper propagation means.
leaf blade having the center of the leaf lower than the margins;
a slight form of seersuckering.
(in Hosta) a single shoot with roots attached.
the leaf distortion caused during the expansion of the
interior of a leaf blade with a correspondingly lesser expansion of the
margin tissue, usually resulting from a narrow white margin and green or gold
center; i.e. H. ‘Lunar Eclipse’.
having shoots above the ground. eye - an undeveloped or dormant
shoot; dormant bud.
a flattening of the flower stem, most frequently at the top,
giving the appearance of several scapes
together side by side.
1. application of nutrients. 2. union of egg and sperm.
the long thin part of the stamen; male flower part that holds the
the main stem of the inflorescence.
bent upward parallel to midrib, keelshaped.
(in Hosta) having leaves with edges or sides curled in to the
midrib; i.e., H. ‘Stetson’.
the genetic make-up of a plant.
taxonomic division of related species below family.
smooth hairless leaf texture.
having a waxy coating (or bloom) producing a white to blue
coloring over the plant parts.
shaped like a valentine heart; cordate.
a seedling from two distinct genotypes.
the flowering part of a hosta including the raceme, peduncle,
pedicel and flower.
(in Hosta) the larger, occasionally flat, leaf-like
structures on the flower stem.
(in Hosta) having a margin variegation that is not uniform, but
irregularly extends into or toward
the center of the leaf; i.e. H. montana 'Aureomarginata', H. montana'Choko Nishiki'.
(in Hosta) pre-adult stage usually exemplified by more pointed,
narrower leaves, fewer vein pairs, thinner marginal variegation, faster
growth rate, and often smaller leaves and clump size.
