Spring is just around the corner– in fact it’s Friday March 20. In preparation for that date, the people who plan the “National Days” calendar designated March 12th as the day to participate in National Plant a Flower Day
Each year this day is dedicated to the planting of flowers and looking forward to the spring season. Flower gardening has become a hobby for many, young and old, and National Plant a Flower Day is a start to the new season each year.
If you do go along with this National Plant a Flower Day and you live in St. Louis, you better make sure you pick the right flowers. According to the Farmers’ Almanac, the average last spring frost in St. Louis typically occurs around April 7 to April 12, depending on specific location data. For most, this means tender flowers and annuals should not be planted in March.
Typically you can start planting hardy flowers and pansies as soon as the ground gets soft in March. It is generally safe to plant cold-hardy plants in March. Plants with a cold-tolerance include pansies, dianthus, and snapdragons. It’s also probably safe to plant violas, sweet alyssum and perennials like day lilies, coneflowers and hostas. Those plants generally take the possible freeze that St. Louis could experience in late March early Aril.
For most annuals and tender plants, wait until after the last frost, which is typically between April 15th and April 20th.
