Daisy white button (Mauranthemum paludosum) is also known as mini-marguerite and the snowland annual chrysanthemum. It is a low-growing, mounded, annual flowering plant that can grow to about 12 inches tall. Daisy white button is an indigenous plant to Spain and Portugal and is hardy in all zones. Daisy white button has 1 to 1 1/2 inch wide, white flowers that resemble the blossom of a Shasta daisy. Plant daisy white button plants in full sun and provide them with well-draining soil. In Florida, daisy white button can be grown as a winter annual. Plan on starting daisy white button seeds in September, and planting them outside in October.
Spread out into a seed starting tray a quality, sterilized, seed-starting potting mix. Use the base of a 3- or 4-inch pot, a square of wood or the base of your hands to pack down the seed starting mix until it's well compacted. Or you can make your own seed starting mix by mixing together equal portions of sterilized potting mix, aged compost, fine sand, vermiculite or perlite and peat moss.
Moisten the growing media in the seed starting tray thoroughly. It should be moist to the touch, but not soggy wet.
Sprinkle the daisy white button seeds onto the soil in the seed starting tray. Try to plant the daisy white button seeds so they are spaced about 1/2 inch apart. Or you can create shallow rows and space each row about 2 inches apart. Plant the daisy white button seeds 1/2 inch apart in each row.
Press the daisy white button seeds into the seed starting mix using your fingertips or the eraser end of a pencil. Spray the surface of the soil with a fine mist of water.
Transfer the tray to a well-lit area of your home. Ideally, there should be approximately 8 to 10 hours of light a day, but refrain from providing direct sunlight. The temperature range for germination needs to be between 60 and 70 degrees F. Germination of daisy white button seeds is typically between 7 and 14 days. Keep the soil in the tray leaning toward the moist side; mist the soil with water as needed.
Thin out the daisy white button seedlings when they have approximately one pair of leaves each. Snip off at the base of the stem the spindlier seedlings, leaving the hardier seedlings so each plant is spaced 1 1/2 to 2 inches apart. Transplant the daisy white button seedlings when they've reached about 1 to 1 1/2 inches tall. You can plant them directly into containers, or in drifts, beds or as borders in your flower garden.
