Isotoma axillaris Glowing Violet ['Tmlu 1301'] PP28,511 (Fizz N Pop Violet Blue Stars) - A compact herbaceous perennial that grows to 1 foot tall by 18 inches wide with fine textured feathery divided medium-green leaves. From mid spring until first frost this plant is covered with star-shaped 1 1/2" wide yellow centered violet flowers that rise above the foliage. Plant in full sun to partial shade in a well-drained soil and give regular to periodic irrigation. Possibly root hardy to below 25F but best in warmer locations in USDA Zones 9 and above. Trim back spent blooms and fertilize to encourage repeat blooms late into the fall. In mild climates this plant will return as a perennial but it is not typically long lived (expect 2 to 3 years) but it is sensational while it lasts and longevity can be prolonged by cutting back hard in late fall. Use care not to get sap on skin or in the eyes when handling as some are quite sensitive to the sap of this plant. It is also considered poisonous to livestock. A beautiful showy plant for the border, mixed container planting or rock garden accent that is nectar rich and attractive to bees beneficial pollinating insects to your garden. The species Isotoma axillaris has a wide distribution on rocky soils in eastern Australia. The name for the genus comes from the Greek words 'isos' meaning equal and tomos meaning "a cutting" or a "slice" in reference to the equal petal lobes, which distinguish it from related plants in the genus Lobelia (both genera now placed in the Campanulaceae). The specific epithet is a reference to axillary flowers, meaning they form in the leaf axils. Common names include Australian Hairbell, Rock Isotome, Blue Stars, Star Flowers or Showy Isotomic and sometimes is referred to a Laurentia, which comes from its previous scientific name, Laurentia axillaris. This cultivar was bred by storied British horticultural company Thompson and Morgan and had its origins in their seed breeding program initiated in the 1990s at their Ipswich, Essex, UK location. Though no cultivars were initially selected or introduced earlier, in 2010 seedlings from this program were used for further breeding with the objective of developing plants with larger and novel colored flowers over a long season without the need for a vernalization. Two cultivars came out of this program 'Tmlu 1301', with large deep purple flowers and prolific basal and lateral branching was given the marketing name Glowing Violet and 'Tmlu 1401' with bright pink flowers is marketed as Pretty in Pink and collectively these plants are part of Thompson and Morgan's Fizz N Pop Series. At this time (October 2018) only 'Tmlu 1301' has a US plant patent (PP28,511) but 'Tmlu 1401' has a patent pending (PPAF). In our trials of these two plants 'Tmlu 1401' bloomed earlier in mid spring while 'Tmlu 1401' came on a month later in late spring. This plant is marketed in the US by PlantHaven.  The information on this page is based on our research that has been conducted on this plant in our nursery library, from online sources, and from observations made of the crops growing in the nursery, plants in the nursery's garden and those in other gardens where we have observed it.
