We grow and sell what are known in the trade as tubestock plants.
You can see two here; and examples of each tubestock plant on almost every product page.
Tubestock is a technical horticultural term for young plants, usually between 5cm and 15cm tall (obviously depending on the type of plant).
They are grown from a cutting, seed, or Tissue Culture, with a healthy strong root system ready for immediate planting in your garden.
Tubestock plants are not seedlings - they are much larger and far more mature than a seedling, and are usually not grown from seed.
They are the plant size used by professional landscapers, horticulturalists and revegetation gardeners.
