Monstrosum Mix Strawflower Seeds

Originally native to Australia and often referred to as "paper daisy", the strawflower has a rich history dating back centuries. Its name comes from the straw-like appearance of its flowers, which retain their colour and form even after drying, making them excellent for decorative purposes long after harvesting. 

The Monstrosum Mix strawflower is usually cultivated as an annual in our Canadian climate, although it can be grown as a perennial in zones 9-11. Its ease of growth makes it suitable for both experienced and novice gardeners.  The upright plants reach 2 to 3 feet in height, producing a profusion of vibrant flowers in shades of white, yellow, orange, pink, and red.

Ideal for warm and sunny climates, the Monstrosum Mix Strawflower is relatively drought-tolerant once established. Regular watering during prolonged heat ensures healthy growth and continuous blooming. The long-lasting flowers also attracts pollinators, such as butterflies and bees, enhancing biodiversity in the garden.

The blooms last for weeks, retaining their colour and form, making them perfect for fresh arrangements or dried displays like wreaths and bouquets.

GROWING INSTRUCTIONS

Despite their bland-sounding common name, blooms of the strawflower never disappoint. The Australian native is a member of the aster family and, will dazzle your flower beds with vibrant shades of all colors.

Seeds can be started indoors 6-8 weeks ahead of the last frost in your area. Sow seeds into seed starting flats or plant a few seeds into individual starter pots. Slightly press them into the seed starting medium to ensure good contact and mist well. Don’t cover the seeds, light exposure will help them sprout quickly. 

Seedlings should begin to germinate in 7-10 days and can then be transferred to a bright windowsill or better yet, under fluorescent grow lights where they can receive up to 16 hours of light per day. Keeping the medium evenly moist, seedlings will grow aggressively anticipating their late spring transplant. When seedlings get to be 5-10 cm tall, thin them out, leaving one plant per 25-30 cm. 

Leading up to the last frost date, seedlings can start to get a taste for the outdoor elements. Gradually harden them off for at least a week before transplanting when you’re sure no late frost will sneak in. Getting them established as soon as possible is important to make the most of their beautiful blossoms, but don’t rush the fragile seedlings into still-cold soil. Raised beds, cold frames or clear plastic coverings will help warm the soil early in the season. 

Choose a site that recevies full sun for your strawflower transplants. This will result in sturdy stems and maximize potential blooms. The soil should be well-drained and tilled deeply to about 30 cm with some compost mixed in. Otherwise, strawflowers aren’t too particular about soil type or fertility. 

Extremely drought tolerant once established, strawflowers will need 3 cm of water per week, but only if they don’t receive any rain. They hold up well to sun and heat, but prefer low humidity and temperatures around 21 degrees. Strawflowers will not tolerate frost.

Strawflowers are not heavy feeders but a monthly fertilizing regimen will ensure they bloom prolifically throughout the season. If kept in containers, consider a more frequent feeding schedule. 

Flowers should be harvested or deadheaded continuously to get the best yields. Cut blooms when 2-3 layers of petals have unfolded but before the entire flower opens up. 

Strawflowers’ bright colors and stiff, papery petals result in very attractive dried flowers. Their height and showstopping daisy-like blooms are perfect for borders and at the back of flower beds.
