Seeds Jargon

  • F1 Hybrids: hybrid seeds are produced from two specially selected varieties that are kept in isolation. As they are produced from only two plants, seeds are almost identical genetically.
  • Open Pollinated: open pollinated plants aren't isolated from other varieties, so are more genetically diverse.
  • Heirloom: heirloom seeds are historic, some going back to Victorian times, others more recent. Heirloom varieties can be good or bad, depending on how careful the breeder is to maintain genetic similarity.
  • Hybrids vs Open Pollinated

    As hybrids are produced from two specially selected varieties, the quality is more consistent, with a higher germination rate and improved cropping. But, as they require time, resources and know-how to create, they come to the market at a higher cost. They are also genetically unstable, and so if you keep the seeds from the resultant crop, performance is usually poor. Open Pollinated seeds are highly diverse and have often been grown for successfully for decades. Seeds from the resultant crop are usually perform well.

    Annual, Biennial and Perennial

    Annual plants complete their life cycle within a year, biennials in two years (usually only flowering in the second year) and perennials can live on indefinitely.

    Hardy, Half-Hardy and Tender

    Hardy and half-hardy plants can survive a light frost, but the latter are best moved indoors during periods of bad weather. Tender plants must be kept indoors, until after the last frost.

    We believe that anyone, regardless of ability can successfully grow their own plants at home, and do so in an eco-friendly and sustainable way.

How your order will arrive
Please see our below guidance on your perennial or alpine's care:

  • Watering: During your perennial or alpine's first growing season, you should provide them with frequent waterings. Try to also avoid wetting the foliage to reduce the risk of disease.
  • Deadheading: To promote a long flowering period, you should deadhead any flowers that appear spent. Simply rescind each flower at their base, taking care to not cut other parts of the plant.
  • Dividing: To really flourish, your perennials can be divided every three to four years. They can be divided when they begin to show less flowers, or appear less healthy in the middle. Make sure to only do so when they aren't currently flowering.

    • Hardiness: these hardy annuals have good resistance to frost.
    • Planting In Pots: suitable for planting in pots.
    • Position: plant in full sun for best results.
    • Soil Types: plant in pre-watered finely prepared soil for optimal growth.
    • Germination Requirements: ideally temperature should be 21-30°C.
      • Planting Distance (Seed Tray): sow 1.5cm (1/2in) deep in pots of compost (or equivalent distance); label noting planting date and variety/species.
      • Planting Distance (Ground): sow 2 seeds 1.5cm (1/2in) deep 45cm (18in) apart.
      • Soil Preparation: remove any stones from the soil and dig in some fertilizer.
      • Thinning: if 2 seedlings grow from one hole remove the weaker plant, or transport if desired.
      • Pest Control: use a pesticide spray to protect from pests.
      • Watering Requirements: water regularly, particularly in dry weather.
