Hosta growers sometimes use some peculiar words ( or use words in peculiar ways ) to describe their particular passions. here are some you might come across .

  • Crown The woody rootstock that stores the energy for the abeyant hosta. normally apparent in a hosta with 3 or more eyes ( see definition below ). Hostas are divided by splitting the crown to leave one or more eyes in each assemble. formally, the crown may be called a rhizome, but never a bulb .
  • Eye A growing shoot from the pate, supporting 1 ( rare ) to possibly 12 leaves. The new eyes are apparent as conic projections from the crown in early spring. besides sometimes called divisions, but this is confusing when referring to a plant that has just been divided. Hosta growers will discuss their hosta sizes based on the number of eyes, but recognize that a hosta with 3 small eyes may have less presence in the garden than one with 1 large eye .
  • dormant Eye/Bud These can be seen by careful examen of the crown. dormant eyes can be forced out of quiescence, for example, if the main eye is damaged ( by predators or a hazardous proficiency called Rossizing ) or if the crown is treated with a increase hormone like BAP-10. These dormant eyes are what are cautiously ( surgically ) isolated for use in Tissue Culture ( TC, see below ).

    Reading: Hosta lingo

  • Petiole The stem that attaches the leaf to the peak. The characteristics of the petiole ( flat, winged, etc. ) can help in identifying hostas. Hostas with spotted or evening purple/red petioles are hot right now, as breeders attempt to carry the crimson color into the leaf of the plant .
  • Flush A set of leaves arising from the center ( randomness ). A hosta may produce 2, 3, or more flushes from each eye during a season. In some hostas, the subsequently flushes will have a slenderly different appearance from earlier flushes ( for example, late flushes of ‘Undulata ‘ may show brumous green centers preferably than the white centers of spring leaves ).

  • Scape The bloom stalk. Again, the characteristics of the shaft can help identify the hosta. Some hostas are known for foliate scapes, meaning that smaller leaves may be attached along the shaft ( see below ). sometimes hosta that are not known for this do it anyhow .
  • Pedicel The inadequate stem that connects the bloom to the scape. Pedicels are supported by bracts, which may be big or minor.

  • Tepal For hosta flowers, what you may think of as petal. Most hostas have six. A combination of “ petal ” ( inner petal ) and “ sepal ” ( outer petal ) .
  • Pod The fruit that forms after the hosta flowers. normally called “ seed pod, ” but there is “ pod parent ” meaning the female partner in a breed pair ( the one with ovaries who bears the fruit ). note that some hostas are basically sterile and may never make pods .
  • Tetraploid Tetraploidy is the trait of having twice a many chromosomes as what is “ normal. ” normally, the pollen provides one set of chromosomes from the male implant ( pollen rear ), the ovary provides a arrange from the female plant ( pod parent ), so the semen has a dispatch laid of chromosome pairs ( and so is called diploid ). Either by natural or biochemical manipulation of the cells in the plant, it is potential to have plants with two ( identical ) sets of chromosomes in each cell. In hosta, there is a species which is naturally tetraploid : ventricosa ( which has the rare capability to produce sow by apomixis, or asexual means without profit of pollen ). By treatment of tissue cultures, hostas can be “ converted ” to tetraploidy, but this has n’t been done in hosta ampere much as it has, say, in daylilies. Tetraploid plants broadly have more energy, meaning, larger blooms, and so forth, but in fact do not much grow ampere big as their diploid generator hosta. ( Compare diploid ‘Sea Thunder ‘ with tetraploid ‘American Sweetheart ‘ at the Hosta Library, for model. ) A drawback of tetraploid plants is that the pollen is importantly larger ( to hold the extra chromosomes ) and so is unmanageable to use in breeding new hostas. Triploid hosta result from crossing diploid with tetraploid plants, and are effectively aseptic. For those of you with unending curio, a late scientific article tested species and cultivars for ploidy .
