Why Grow Antirrhinum From Seed?

Plant Antirrhinum flowers freely through the garden as their intense colours will light up many different aspects of your outdoor space. Sutton’s delight in presenting a fantastic range from ‘Crackle & Pop mix’ with its mixed colours and lower growing height, makes it great for containers. To ‘Chuckles’, a mix of reds, pinks, yellows and whites. Or the fantastic ‘Day and night’, something a little bit different with its deep crimson flowers with a white base.

Growing Antirrhinum from Seed 

Treat Snapdragon flowers as a half-hardy annual, which means it needs growing in a protected environment until the danger of frost has passed.

  • Start sowing antirrhinum seeds in seed trays in a heated propagator on window-sill. Label your trays for easy identification of the plants. Do not cover seed over as they need light to germinate. You can also sow direct after a chance of frost has passed
  • Prick out the seedlings once they are at two-leaf stage, into a decent peat-free potting compost, fibre compostable starter cells are a good choice to grow on the plants. As late spring arrives, harden off by airing outside during the day or by placing in a cold frame.
  • Snapdragons like sunny well-draining soil. Add all-round plant food, a balanced slow-release fertiliser added to the soil. Add organic matter in open ground, especially if the soil is on the heavy side.
  • Because of their bright colours and attention-demanding nature, try dotting in among a mixed border or in drifts of plants. If space it tight, fill out a container.
  • Watering regularly while plants are establishing and feeding with Seaweed extract in the first months of summer will help establish these plants

It’s important when flowers are forming to deadhead, or they will set seed and flowers will stop blooming early. Antirrhinums can suffer from powdery mildew, so pick over any greying leaves. A Potash feed during mid-summer will encourage flowering.

How Long Do Antirrhinum Seeds Take To Germinate?

Antirrhinum seeds should germinate within 10-20 days. Transplant your seedlings 5 cm apart in seed trays and grow on. Gradually acclimatise the Antirrhinum plants to outside conditions before planting out 15cm apart in a sunny position.

Used as dot plants in groups of threes, surrounded by other lower bedding plants is a traditional way to grow heavy flowering summer plants. Antirrhinum are available in four varieties, the Dwarf Antirrhinum is ideal for Rockeries, Intermediate is ideal for cut flowers and taller varieties for the back of the border and trailing from hanging baskets. Antirrhinum naturally live in rocky areas so will take in a dry area. This is an easy plant to grow and is a great plant for children to grow.
